FIELD OF THE INVENTION

The invention relates to new imides, to a plurality of processes for their preparation, and to their use as fungicides.

BACKGROUND OF THE INVENTION

It is known that certain imides which are similar to those mentioned below have fungicidal properties (cf., for example, EP-A 398692, EP-A 528681 and WO 97-00856). However, the action of these compounds is not entirely satisfactory in all fields of application, in particular when low application rates are used.

SUMMARY OF THE INVENTION

Novel imides have general formula (1)

in which

X represents halogen or alkoxy and

Z represents optionally substituted aryl or a group

 in which

R¹ represents optionally substituted alkyl, cycloalkyl or arylalkyl,

R² represents optionally substituted alkyl, aryl, cycloalkyl, arylalkyl, heterocyclyl or heterocyclylalkyl,

Z¹ represents a single bond, oxygen, sulphur or a group

Aryl represents aromatic, mono- or polycyclic hydrocarbon rings such as by way of example and preferably phenyl, naphthyl, anthranyl, phenanthryl, preferably phenyl or naphthyl, in particular phenyl.

Furthermore, it has been found that the new substituted heterocycloalkenes of the general formula (I) are obtained when

carboxamides of the general formula (II)

in which

Z is as defined above,

are reacted with an carbonyl halide of the formula (III),

in which

X is as defined above, and

in each case if appropriate in the presence of a diluent and in each case if appropriate in the presence of an acid binder.

Finally, it has been found that the new carboxamide derivatives of the general formula (I) have a very potent fungicidal action.

If appropriate, the compounds according to the invention may exist as mixtures of various isomeric forms which are possible, in particular stereoisomers such as for example, E- and Z-isomers but, if appropriate, also in the form of tautomers.

Depending on their particular physical and/or chemical properties, the active compounds can be converted into the customary formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols, microencapsulations in polymeric substances and in coating compositions for seed, and ULV cold and hot fogging formulations.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is, liquid solvents, liquefied gases under pressure, and/or solid carriers, optionally with the use of surfactants, that is, emulsifiers and/or dispersants and/or foam formers. In the case of the use of water as an extender, organic solvents can, for example, also be used as auxiliary solvents. The following are mainly suitable as liquid solvents: aromatics such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics or chlorinated aliphatic hydrocarbons such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons such as cyclohexane or paraffins, for example, mineral oil fractions, alcohols such as butanol or glycol and their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents such as dimethylformamide and dimethyl sulphoxide, or else water. Liquefied gaseous extenders or carriers are to be understood as meaning liquids which are gaseous at ambient temperature and under atmospheric pressure, for example aerosol propellants such as halogenohydrocarbons, or else butane, propane, nitrogen and carbon dioxide. Suitable solid carriers are: for example ground natural minerals such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals such as highly-disperse silica, alumina and silicates. Suitable solid carriers for granules are: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, or else synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks. Suitable emulsifiers and/or foam formers are: for example non-ionic and anionic emulsifiers such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, aryl sulphonates, or else protein hydrolysates. Suitable dispersants are: for example ligninsulphite waste liquors and methylcellulose.

Adhesives such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, or else natural phospholipids such as cephalins and lecithins and synthetic phospholipids can be used in the formulations. Other additives can be mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations generally comprise between 0.1 and 95 per cent by weight of active compound, preferably between 0.5 and 90%.

The active compounds according to the invention, as such or in their formulations, can also be used as a mixture with known fungicides, bactericides, acaricides, nematicides or insecticides, for example to widen the spectrum of action or to prevent the development of resistance. In many cases, synergistic effects are obtained, that is, the activity of the mixture is greater than the activity of the individual components.

Examples of suitable components in mixtures are the following:

A mixture with other known active compounds such as herbicides, or with fertilizers and growth regulators, is also possible.

The active compounds can be used as such or in the form of their formulations or the use forms prepared therefrom, such as ready-to-use solutions, suspensions, wettable powders, pastes, soluble powders, dusts and granules. They are used in the customary manner, for example by pouring, spraying, atomizing, broadcasting, dusting, foaming, brushing on and the like. It is furthermore possible to apply the active compounds by the ultra-low volume method, or to inject the active compound formulation or the active compound itself into the soil. The seed of the plants can also be treated.

When applying the active compounds as fungicides, the rates of application can be varied within a substantial range, depending on the type of application. For the treatment of parts of plants, the rates of application of active compound are, in general, between 0.1 and 10,000 g/ha, preferably between 10 and 1,000 g/ha. For the treatment of seed, the rates of application of active compound are generally between 0.001 and 50 g per kilogram of seed, preferably between 0.01 and 10 g, per kilogram of seed. For the treatment of soil, the rates of application of active compound are generally between 0.1 and 10,000 g/ha, preferably between 1 and 5,000 g/ha.

The compositions used for the protection of industrial materials comprise the active compounds in general in an amount of 1 to 95%, preferably 10 to 75%.

The use concentrations of the active compounds according to the invention depend on the species and the occurrence of the microorganisms to be controlled and on the composition of the material to be protected. The optimum rate can be determined by test series. In general, the use concentrations are in the range of 0.001 to 5% by weight, preferably 0.05 to 1.0% by weight, based on the material to be protected.

The efficacy and the spectrum of action of the active compounds to be used according to the invention in the protection of materials, or of the compositions, concentrates or, quite generally, formulations which can be prepared from them, can be increased by adding, if appropriate, further antimicrobially active compounds, fungicides, bactericides, herbicides, insecticides or other active compounds to widen the spectrum of action or to achieve specific effects, such as, for example, additional protection against insects. These mixtures may have a wider spectrum of action than the compounds according to the invention.

PREPARATION EXAMPLES Example (1)

A solution of 2.3 g (0.006 mol) of 2-methoxyimino-2-{2-[1-(4-trifluoromethylphenyl)-ethylideneaminooxymethyl]-phenyl}-acetamide and 0.6 g (0.0075 mol) of pyridine in 20 ml of toluene is heated at approx. 90° C. A solution of 6.5 g (0.06 mol) of methoxyacetyl chloride in 20 ml of toluene is added dropwise at this temperature and the mixture is stirred for 24 hours at 90° C. After cooling, the reaction mixture is extracted by shaking with water. The organic phase is separated off, dried over sodium sulphate and concentrated in vacuo. The residue is chromatographed on silica gel using cyclohexane/ethyl acetate (9:1 to 3:1). This gives 0.6 g (22% of theory) of 2-methoxy-N-(methoxyimino-{2-[1-(4-trifluoromethylphenyl)-ethylideneaminooxymethyl]-phenyl}-acetyl)-acetamide of melting point 134-138° C.

Example (2)

A solution of 2.3 g (0.006 mol) of 2-methoxyimino-2-{2-[1-(4-trifluoromethyl-phenyl)-ethylideneaminooxymethyl]-phenyl}-acetamide and 0.6 g (0.0075 mol) of pyridine in 20 ml of toluene is heated at approx. 90° C. A solution of 6.8 g (0.06 mol) of chloroacetyl chloride in 20 ml of toluene is added dropwise at this temperature and the mixture is stirred for 24 hours at 90° C. After cooling, the reaction mixture is extracted by shaking with water. The organic phase is separated off, dried over sodium sulphate and concentrated in vacuo. The residue is chromatographed of 3 silica gel using cyclohexane/ethyl acetate (19:1). This gives 0.3 g (11% of theory) of 2-chloro-N-(methoxyimino-{2-[1-(4-trifluoromethylphenyl)-ethylideneaminooxymethyl]-phenyl}-acetyl)-acetamide of melting point 92° C. (decomp.).
